Making her return to the dance floor after suffering a mild concussion during last Monday's performance, Melissa Gilbert only earned two more points than DeGraw with 21/30. The Little House on the Prairie star, 47, and her dance pro Maksim Chmerkovskiy danced the salsa -- and Inaba said there was "an element of control that was lacking."

Gladys Knight rounded out the bottom three earning 22/30 points for her samba with partner Tristan MacManus. Tonioli said he loves watching the legendary singer, 67, dance, but Inaba pointed out the soul singer made "a few tiny mistakes."

However, Inaba added, "There's a reason you are the legend that you are."
